distraction

why am i so easily distracted? especially so easily distracted from SLEEP. musings on my toxic workplace (...mentally and emotionally; not chemically) were superceded by checking out facebookery, then past costumery, and finally long past bloggery. and then, yet again, i fail to learn that sleeping is necessary in order to wake up again ...in a non-late, non-brain-dead, non-lose your job kinda way... when? when will i learn?
